"I'm Still Here"

In 2009, actor Joaquin Phoenix, dressed in a suit and a beard and looking almost comatose, appeared on "The Late Show With David Letterman" and announced he had quit acting to pursue a hip-hop career. The next year of his life was filmed by his brother-in-law, actor/director Casey Affleck, for the documentary "I'm Still Here." The film, which was advertised as being real, was panned by the L.A. Times as "far from the Joaquin Phoenix you're used to seeing onscreen: Snorting cocaine, ordering call girls, having oral sex with a publicist, treating his assistants abusively and rapping badly." Shortly after the movie was released, Affleck revealed the whole thing to be a joke. We were relieved, because Phoenix's rapping was shockingly terrible.
